cactus pleco??

I prefer not to keep plecos or otos with my discus.
 
to keep plecos properly, they need to be fed a diet with lots of fresh veggies or some protein (depending on the kind). feeding them right usually means that water quality will be less than great, as they eat a lot and poop a lot. if you don't feed them (trying to maintain perfect water parameters), they are likely to go after the slime coat on your discus.
